Attaching the TP-BUS core
1. Remove the lock indicated in Fig. 1-13 (a) and split the core into halves.
2. Wrap the twisted pair wire once around one of the core halves.
Wrap the wire so that the distance between the core and the connector is within
30 mm. See Fig. 1-13 (b).
3. Close the core keeping the twisted pair wire from being wedged in
between.
See Fig. 1-13 (c).
4. Check that the core is securely locked.
5. Attach other cores in a similar fashion.

1.8.2 Setting the TERMN Switch
• If the TERMN switch is not set properly, communications become unstable
and erroneous operation may result.
Set the TERMN (termination) switch on the device at the end of the TP-BUS
located opposite to the control unit.
Taking Fig. 1-11 as an example, the TERMN switch on the unit frame at the end of
the TP-BUS is turned on, and the TERMN switches on all other units are turned off.
There is no TERMN switch on the control unit. This is because the control unit is
designed on the assumption that it be connected to the end of the TP-BUS. The
internal termination of the control unit is always on.
